Luigi Manon has been charged with multiple counts of murder, including first-degree murder and murder as an act of terrorism, for the killing of United Healthcare CEO Brian Thompson. The charges were announced by Manhattan District Attorney Alvin Bragg and NYPD Commissioner Jessica Tish. The murder was described as a premeditated and targeted act intended to cause shock and intimidation. Manon allegedly used a 3D-printed ghost gun to carry out the murder. The case highlights the growing concern over ghost guns, which are untraceable and increasingly prevalent in New York City. The prosecution will need to prove that the murder was intended to send a larger message, possibly related to the healthcare industry, as indicated by Manon's writings. The case has drawn significant public attention, partly due to social media praise for the act, which officials condemned as a celebration of violence. Manon is currently in Pennsylvania, awaiting extradition to New York to face charges.
